In many countries, local governments struggle with inefficiency and corruption, often perpetuated by entrenched elites. This paper explores how leadership changes affect local bureaucratic performance by combining personnel and citizen surveys with a regression discontinuity design in a large sample of Indonesian villages. The findings show that turnovers in village elections revitalize local bureaucracies, disrupt nepotistic networks, and improve local government performance. Bureaucrats serving new leaders are more engaged and less likely to be tied to past or present village officials, resulting in a more responsive bureaucracy that interacts more with citizens and better understands their needs. This improves public service provision, measured in both administrative data and citizen surveys. Overall, our results show that leadership changes can mitigate elite capture and improve governance at the grassroots level.
